  • TIDA-010080: Design help

    Resolved
    Part Number: TIDA-010080 Hi Experts, I am interested in using just the LLC stage and the output SR stage for a 600W DC-DC design. How would I calculate the input capacitance if I do not use a PFC stage? Regards, Gautham Venkat

  • RE: UCC28180: Schematic review

    Thanks for your answer, Harish. We will double check the inductor value, thanks again for your support! do you think this could be the reason behind the damaged PFC ICs? The auxiliary flyback is taken from an application note (fully replicated) TIDA…

  • RE: UCC28019: PFC Circuit PFC Circuit Unidentified Error

    Resolved
    Hi Cihangir, Manganese-Zinc alloy is used in ferrite cores. What you have is a gap-less ferrite and not really the inductor that you are expecting at these currents. A ferrite will saturate almost immediately. For example, flux density = LI/NA. Assuming…
